After spending a few hours searching through the images of the usual websites, I gave up when I couldn't find it and started googling by description... Found it. Meruliopsis taxicola is the name and there are several other websites with images. I'll post this one - https://en.wikipedia.org/wiki/Meruliopsis
@rhoing Thanks, Thom!
@koalagardens LOL! It's only on the dead branches.
